Wiley X Trek Features The Wiley X Trek is built around a super tough Triloid nylon frame engineered to flex and absorb impact while still accommodating a higher range of prescription lenses than most high wrap sport frames allow. This flexibility makes the Trek a practical choice for shooters and outdoorsmen who need corrective lenses without giving up the wraparound protection a sport frame provides. The polarized polycarbonate lens is finished in a blue mirror coating that reduces glare off water snow and other reflective surfaces while preserving natural color contrast. Polycarbonate construction also resists impact far better than standard glass or acrylic lenses an important trait for anyone working or recreating around debris or bright sun. A modern rectangular lens shape gives the Trek a contemporary look that moves easily from the range to everyday wear. Flattering stem detailing rounds out the frame s sporty go anywhere aesthetic without adding unnecessary bulk or weight. Sized medium to large and finished in gloss crystal dark gray the frame is built to fit comfortably across a wide range of face shapes and sizes.
